We explore the cosmological consequences of Modified Gravity (MOG), and find that it provides, using a minimal number of parameters, good fits to data, including CMB temperature anisotropy, galaxy power spectrum, and supernova luminosity-distance observations without exotic dark matter. MOG predicts a bouncing cosmology with a vacuum energy term that yields accelerating expansion and an age of ~13 billion years.

Regular Rotating Black Hole: Probing the boundaries of the Radiative Signatures and Jet Power
astro-ph.HE 2025-08 conditional novelty 5.0 of 10

MOG regular rotating black holes are compatible with most X-ray binary data only for beta below about 0.38 to 0.4, and are excluded for the near-extremal source GRS 1915+105.
